摘　　要：根据导弹-目标追逃问题的相对运动学关系,基于反演思想设计了双滑模变结构导引律,运用自适应方法实现对制导系统参数不确定性和目标机动的估计,该导引律能够保证导弹在击中运动目标的同时满足期望落角;然后运用Lyapunov稳定性理论分析了该制导律进入平衡状态的充分条件。仿真结果表明了该设计方法的有效性。According to the relative movement relation of pursuit-evasion problem of missile against target, a double sliding mode guidance law based on backstepping is proposed. The guidance law can guarantee the missile to hit the moving target at a desirable azimuth. A sufficient condition of entering to the state is analyzed by using Lyapunov Theory of Stability. A self-adaptive method is used to estimate the unknown information during the flight, such as target acceleration and system parameters, then, the robustness to target maneuvering is achieved, which can reduce the miss distance. The simulation results are presented to show the validity of the proposed method.
